Pimoroni PIM357 BME680 Breakout Air Quality Sensor

SKU CH-6EXW-KNCHR

Monitors temperature, pressure, humidity and indoor air quality via a Bosch BME680 sensor with I2C address selection and Qwiic/STEMMA QT connector for Raspberry Pi and Arduino

  • Monitors temperature, pressure, humidity and gas resistance with the Bosch BME680 sensor
  • Selectable I2C address 0x76 or 0x77 via ADDR solder bridge
  • Qwiic/STEMMA QT connector on boards from 2021 for plug-and-play wiring
  • Works with 3.3 V or 5 V logic and includes reverse polarity protection
  • Raspberry Pi-compatible pinout and Arduino support with Python library

BME680 Environmental Breakout

The Pimoroni PIM357 breakout board carries a Bosch BME680 sensor that measures temperature, pressure, humidity and gas resistance. It connects via I2C with an address selectable between 0x76 and 0x77 using the ADDR solder bridge. Boards made from November 2021 include a Qwiic/STEMMA QT connector for solderless wiring. The board works at 3.3V or 5V and includes reverse polarity protection.

Makers monitoring indoor air quality

This breakout suits hobbyists and developers who want to log volatile organic compound trends alongside temperature and humidity on a Raspberry Pi or Arduino. It is not for projects that require calibrated CO2 concentrations, particulate counts or certified air-quality reporting. Buyers needing multi-gas detection or industrial-grade accuracy should look at dedicated instruments.

Fits Pi pinout and Qwiic ecosystems

The pin header matches Raspberry Pi pins 1, 3, 5, 7 and 9 so the board plugs directly onto a Pi GPIO header or a Breakout Garden slot. The Qwiic/STEMMA QT port lets you daisy-chain additional I2C devices without a breadboard. A Python library is available for Raspberry Pi and the sensor is also supported in the Arduino ecosystem.

Questions about this item

What host pins or connectors must I have free to attach the PIM357 BME680 breakout?

The board uses an I2C bus and fits Raspberry Pi pins 1, 3, 5, 7, 9; boards made from November 2021 onwards also include a Qwiic/STEMMA QT connector for plug-and-play use.

Will the sensor work on a 5 V Arduino Uno as well as a 3.3 V Raspberry Pi?

Yes, the breakout is 3.3 V or 5 V compatible and includes reverse polarity protection, so it can be connected directly to either voltage level.

How do I confirm the BME680 is communicating after wiring it up?

Scan the I2C bus for address 76 or 77 (set by the ADDR solder bridge), then read temperature, pressure, humidity and gas resistance registers to verify live data.
